Coach Ole Wener will have to do without Ömer Toprak when his Werder side take on FC Nürnberg on Sunday afternoon (13:30 CEST). The central defender, who returned to the side against St. Pauli after a spell on the sidelines, picked up another calf injury in the week and will subsequently be unavailable for the weekend’s game. Toprak will undergo further examinations in order to get a full-scale diagnosis.
